ONE HOUR ENAMEL is an incredibly tough, fast drying, acrylic enamel for interior and exterior use on surfaces that require quick return to service and an abrasion resistant finish. It is water thinned so it poses no fire hazard or objectionable odor. The product is based on a specialized acrylic resin that dries quickly to a tough, durable, film that has excellent weather, blocking and abrasion resistance along with superior adhesion properties. With its quick dry, quick sand, and quick re-coat times, ONE HOUR ENAMEL helps you get the job done faster than conventional acrylic finishes. The product's superior resistance to blocking means that you will be able to put doors and windows back in service much quicker than with competitive acrylic finishes.
